A Button Challenge

The A Button Challenge, ABC for short, is a challenge in which the number of presses of the A button is minimized, whether on a per-mission or a per-file basis. Because the A button makes Mario jump, great creativity and precision are required to progress in the game without using this "vital" function. The ABC is often connected to the discoveries of new glitches and techniques that can be used more generally throughout the game. Much of the material on the pannenkoek2012 and UncommentatedPannen channels is related to the A Button Challenge, with only 27 remaining A presses (18 unique A presses) left to optimize.
